FRUIT-JAR.

- SPECIFICATION forming part of Letters Patent No. 312,595, dated February 17, 1885.

Application filed April 17, 1884. (Model.)

. enable others skilled in the art to make and use the said invention.

This invention relates to jars and other vessels for preserving alimentary substances by excluding air therefrom, and has for its object the more effectual guarding against ingress of air and of escape of any of the contents of the vessel, and the avoidance of contact of any of the contents with the sealinggasket, either while stored therein or during the emptying of such vessel, and also the cheap ness of manufacture thereof.

The nature of this invention consists in a jar or vessel having a shoulder formed on the neck thereof adapted to receive a gasket, above which shoulder are spiral or helical projections adapted to engage with corresponding helical projections upon the internal surface of the lid, and around and below which shoulder is a rim or rings adapted to receive an encircling elastic band embracing the neck of the jar and also the external surface of the cover, thus forming a duplex seal upon the jar, neither of which seals require grinding to prepare their parts for use.

I will now proceed to particularly describe the mode of making and using the said invention, referring in so doing to the drawings annexed and the letters of reference marked thereon.

Figure 1 shows an elevation of this invention Fig. 2, atop view; Fig. 3, avertical central section; Fig. 4, a top view of the jar-neck with the cover removed; Fig. 5, an inverted view of the cover, and Figs. 6, 7, and 8 show modified forms of the invention in partial sectional elevations.

The same letters of reference apply to the same parts in the several figures.

A is the jar-neck, having a shoulder, B, adapted to receive a gasket, 0. The part of the jar-neck A below the shoulder Bis prefer- 5o ably, but not necessarily, provided with circumferential ridges or rings A, over which an elastic band, D, being applied, fits tightly. The neck of the jar A above the shoulder B is of a reduced diameter, and has helical proj ections or segments E formed thereon by molding. The cover of thejarFis of the same or about the same diameter externally as the part of the jar-neck Abelow the shoulder B, and has preferably, but not necessarily, circumferential 6o ridges or rings F formed thereon. Inside of the cover F are formed two or more (prefererably three) helical projections or segments G on the neck A, adapted to pass between and to fit under the similar projection E, and by ro- 6 5 tating press the rim F of the cover F against the gasket 0 and form a seal. The elastic band D is of such size as to firmly embrace the circumference of the neck A and the cover F, and by pressing on the ridges A and F seals the jar with a second seal. When there are no rings, as shown at A and F, on the jar neck and cover, the same effect is obtained by 7 using the'band D, of such dimensions as to pass over the angle of the top of the cover F and shoulder A of the jar-neck.

To use these jars, the gaskets 0 being placed on the shoulder B, the cover F is placed upon the jar-neck A and rotated so far that the segments G of the cover engage the segments E of the neck and compress the gasket 0 into a close fit,aft'er which the elastic band D is applied and closes off all ingress of air.

As shown in Fig. 6,the rings or circumferential ridges F on the cover F are omitted, and the band D is of such dimensions as to extend over the upper corner, F, of the cover F. As shown in Fig. 7, the rings or circumferential ridges A on the neck A are omitted, and the band D is applied so as to embrace a shoulder or angle, A", on the neck. As shown in Fig. 8, the circumferential rings F on the cover F and A of the neck A are successively of decreasing diameter, so that the cover F may be made in and removed from a mold with an outer shell or bottom formed on a single piece, and the seam of the mold across the bands F avoided.

It is obvious that the covers F in Figs. 1, I shoulder adapted to receive a gasket, helical 6, 7, and S can be used with any of the other bands D and necks A shown and be Within the scope of this invention.

I do not claim herein a Series of circnmt'cifi ential ridges on the cover, and another series on the jar, and an embracing elastic annulus, as this and like matter is the subject of a separate application for Letters Patent by me; but I confine the invention of this application to that of the following claim.

Having described my invention, what I claim 1s In a fruit-jar, the combination of a jar-neck having located below the pouring-mouth a lugs external to the neck, located between the shoulder and pouring-mouth, adapted to engage in corresponding helical projections inside of the cover, with said cover and an interposed gasket, and an elastic inclosing-band embracing and impinged by one or more circumferential shoulders or angles on the cover and neck, substantially as and for the purpose set forth.
